Start by cutting the watermelon into small cubes and removing any seeds if necessary. Measure two cups of diced watermelon and two cups of frozen peach slices. If you’re using fresh peaches instead of frozen, slice them and freeze them for about 30 minutes to help create a thicker smoothie texture.

Place the diced watermelon into the blender first, followed by the frozen peach slices. Add the Greek yogurt and honey if you want extra sweetness. Pouring softer ingredients at the bottom helps the blender mix everything smoothly and prevents the frozen fruit from getting stuck.

Blend the mixture on high speed for 45–60 seconds until completely smooth and creamy. If you prefer a thicker smoothie, add a few ice cubes and blend again briefly. The smoothie should have a silky texture with a soft peach-pink color.

Pour the smoothie evenly into two glasses. Garnish with fresh mint leaves or a small slice of peach on the rim of the glass. Serve immediately while the smoothie is cold and refreshing.
